Not really, just making sure you're in for the long haul. As of now your cast might even be larger than Good Girl Gone Bad.That a bad thing? None can complain either since it will be free, cannot fund the project with Patreon.
As a result, I'd suggest your story, since the montly updates will force you to be episodic, should take a page from GoT, and follow a different protagonist, each of the daughters, and the father, on their various adventures each release.
